Technological progress in uncooled infrared focal plane array sensors have contributed significantly to the broadening of the application of this sensing technique in many fields: Leisure, Manufacturing, Process Control, Building insulation diagnostic, Civil Engineering, Road works, etc. A review of in-situ experiments studied on transport infrastructures over the past decade, advances in measurement system architectures and processing approaches are presented and discussed. Challenges with current uncooled infrared sensor performance and computational requirements are presented and discussed in the context of few selected use cases. Finally, conclusions and perspectives are proposed.
